ROOF-FLANGE.

Specification of Letters Patent.

Patented Nov. 27, 1906.

Application filed May a. 1906. Serial No- 315.155.

To all whom, it may concern.-

Be it known that I, JOHN C. LAUTH, a citizen of the United States, and aresident of Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements in Roof-Flanges, ofwhich the following is a specification.

This invention relates to roof-flanges; and it consists in the mechanismhereinafter described and claimed.

The object of the invention is to provide a roof-flange that can bepacked, if desired, in a knockdown position and that is capable of beingfitted to roofs of different angles and to be easily formed to fit aroof of any of the angles in use.

In the drawings, Figure 1 is an elevation of a roof-flange embodyingthis invention, parts being removed to exhibit construction and partsbeing shown in section. Fig. 2 is a plan view of the plate for saidroof-flange, and Fig. 3 is a cross-section on the line 3 3 of Fig. 1.

One purpose of this roof-flange is so to manufacture it that it will beunnecessary to trim the tubular part thereof in order to fit it to roofsof different pitches. In order to accomplish this, the tube 1 is made intwo halves, which are connected by the seams 2 2. The tube 1 is madeconical, and around it run a series of beads 3, 4, and 5, which beadsproject upward from the outer surface of the tube. Each bead is made ina plane corresponding to the proper plane of intersection of the saidtube with the roofs of a particular pitch, so that when said bead isplaced in the plane of the surface of the roof the tube will bevertical. Near the upper end of the tube is an indentation 6, which isadapted to fit with reasonable closeness upon the pipe 7, with whichsaid tube 1 is intended to be used. The indentation 6 forms the bottomof a socket for the packing 8, so that said packing may be forced in andcovered with melted lead, if desired.

In order to fasten the tube 1 to a roof, a plate 9 is provided having anopening cut into it, whose edge 10 is adapted to fit upon the top of thebead 5. The upper end of the tube 1 is small enough to pass through thesaid perforation, and the edge 10 fits closely upon the top of said bead5. Then, if desired, the plate and the tube may be soldered together,and the plate may be nailed upon the roof 13. In the plate 9 are stampedor otherwise marked contour-lines 11 and 12. The contour-line 11 isadapted to fit upon the bead 4, and the contour-line 12 is adapted tofit upon the bead 3. For use with these last two beads, however, it isnecessary to cut out the plate 9 on the contour-lines 11 or 12, as thecase may be.

If desired, the tube 1 may be made in two parts with the scams 2 2 open,so that the two halves may be nested together for more compact packing.

Each half is stamped up by itself, and the recess 6 and the beads 3, 4,and 5 are pressed into it at the time it is thus formed.

What I claim is 1. In a roof-flange, a tapering tube having a series ofhollow beads around and projecting from one of its surfaces each beadbeing made in a plane corresponding to the intersection with said tubeof the plane of a roof of different pitch.

2. In a roof-flange, a a series of beads around and projecting from itsouter surface, each bead'being made in a plane corresponding to theintersection with said tube of the plane of a roof of different pitch,and a recess around said tube near its top for producing a socket forpacking.

3. In a roof-flange, a tapering tube having a series of beads around andprojecting from its outer surface each bead being made in a planecorresponding to the intersection with said tube of the plane of a roofof different pitch, and a plate having a perforation therethroughadapted to fit upon the upper of,

said beads.

4. In a roof-flange, a tapering tube having a series of beads around andprojecting from its outer surface each bead being made in a planecorresponding to the intersection with said tube of the plane of a roofof different pitch, a plate having a perforation therethrough adapted tofit upon the upper of said tapering tube having beads, and contour-linesupon said plate of difierent pitch, and a plate having a per- Wherebythe said plate may be cut out to fit foration therethrou h constructedto engage IO the respective other beads. an; one of said bea s.
